CATTLE-"GUARD.

Specification of Letters Patent.

Patented Jan. 30, 1906.

To all whom, it ntay concern:

Be it known that we, J OIIN L. FRIEDMAN and JOHN GRAHAM, citizens of the United States, residing at Lawton, in the county of Comanche, Oklahoma Territory, have invented a new and useful Cattle-Guard, of which the following is a specification.

The invention relates to improvementsin cattle-guards The object of the present invention is to improve the construction of cattle-guards and to provide a simple and comparatively inexpensive device of great strength and durability adapted to be readily applied to a railway-track and capable of effectually preventing cattle from passing over it.

A further object of the invention is to pro vide a cattlc-guard of this character adapted to substantially shade the road-bed. to prevent the growth of vegetation, so that cattle will not be attracted to the cattle-guard by any such growth.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood. that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a plan view of a portion of a cattle-guard constructed in accordance with this invention. Fig. 2 is a lon itudinal sectional view taken substantiafly on. the line 2 2 of Fig' 1. Fig. 3 is an enlarged detail perspective view of a portion of one of the sections of the cattle-guard.

Like numerals of reference designate corresponding parts in all the figures of the drawm s.

lhe cattle-guard is composed of central and side sections 1 and 2, located between the rails 3 of a track and at the sides of the track, as clearly illustrated in Fig. 1 of the drawings. Each of the sections is composed of a plurality of large and small rotary guard members 1 and 5, the large guard members being mounted for rotation between the cross-ties 6 and the small rotary members being arranged in pairs above the cross-ties and having their tops disposed in the same horizontal plane as the tops of the large rotary members. The large rotary members are composed of blades 7, provided at their inner longitudinal edges with attachmentflanges 8, which are secured to squared shafts 9 at the faces thereof, as clearly illustrated in Fig. 2 oi the drawings. The terminals 10 of the shaft 9 are rounded to form journals and are arranged in suitable bearings of frame-bars 11. The outer edges of the blades 7 are provided with teeth 12, which are adapted to effectually prevent cattle from passing over the cattle-guard and which are also capable when the guardv members are rotated of cutting down any accidental growth of grass or weeds. The framebars, which are located at opposite sides of the sections of the cattle-guard, are suitably secured to the cross ties and. are connected at their ends by transverse bars 13. The bearings for the shafts of the large rotary members are formed by curved depressions or bonds 14, in which the shafts are retained by upper bearing-plates 15, secured to the upper faces of the frame-b ars. The bearing plates 15 are provided with curved grooves, preferably formed by bending the plates, as shown. The large rotary members, which may be of any desired size, are preferably about nine inches in diameter, and the small rotary members are designed to be about four and one-half inches in diameter, so that the cattle-guard will present a uniform appearance at the top, as clearly shown in Figs. 2 and 3. The small rotary members are provided with blades 16, secured to squared portions of shafts 17. The outer edges of the blades 16 are provided with teeth, and the inner edges have attachm ent-flanges 18,which are secured to the faces of the shaft 17 by suitable fastening devices. The ends of the shafts 17 arejournaled in suitable bearings of brackets 1 9,which are approximately inverted-U shaped, being composed of vertical side portions and connecting top portions. The top portions are provided with depressions or bends to form bearings, and the sides have outturned ends 20, which are secured to the upper faces of the frame-bars The journals of the shafts 17 are retained in the bearing-grooves of the upwardly-projecting brackets by means of upper bearing-plates 21, secured to the tops of the bearing-brackets and extending the entire length of the same. The rotary guard members of the central and side sections are preferably of the same length, the central section being provided with two sets and having a central longitudinal bar 22, arranged in parallelism with the side bars and provided with bearings 23 and having upwardly-projecting bearing brackets 24, mounted on them. The bearings 23 and the bearingbrackets 24 receive the inner adjacent ends of the shafts of the rotary members of the central section of the cattle-guard.

The cattle-guard is designed for use in connection with rails of any size, and is adapted to be readily mounted on the cross-ties, and is capable of effectually preventing stock from passing over it in either direction. It is adapted to prevent any growth of vegetation which might attract cattle as it shades the road-bed, and is also adapted by the rotary movement of the guard members to cut down any chance growth.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A cattle-guard of the class described, comprising large rotary members spaced apart and arran ed between the cross-ties of a track, and sma l superimposed rotary members located between the large rotary members and arranged above the cross-ties.

2. A cattle-guard of the class described, comprising large rotary members spaced apart and arranged between the cross-ties of a track, and small superimposed rotary members located between the large rotary mem bers and arranged above the cross-ties,'the tops of the said small rotary members being arranged in substantially the same plane as the tops of the large rotary members.

3. A cattle-guard of the class described, comprising large rotary members operating in the spaces between the crossties, and small superimposed rotary members arranged in pairs in spaces between the large rotary members for operation above the cross-ties.

4. A cattle-guard of the class described,

comprising a frame secured to the cross-ties of a railroad-track and provided with bearings, large rotary guard members located in the bearings and arranged between the crossties, bearing-brackets extending upward from the frame and located above the cross-ties, and small rotary members supported by the bearing-brackets and located between the large rotary members' 5. A cattle-guard of the class described, comprising a frame having side bars provided with bearings, large rotary members operating between the cross-ties of a. railroad-track and mounted in the bearings 'of'the frame, substantially inverted U -'shaped bearingbrackets mounted on the frame between the said bearings and provided at their tops with bearings arranged in pairs, and small rotary guard members arranged in pairs between the large guard members and journaled in the bearings of the brackets.

6. A cattle-guard of the class described, having rotary guard members, each composed of a polygonal shaft having flat faces, and radially-arranged blades extending from the shaft and having theirinner edges bent at right angles to form flanges which are secured to the said faces of the shaft.

7. A cattle-guard of the class described composed of a series of rotary members,so1ne of which are mounted on the ties and others of which are located between the ties.

8. A cattle-guard of the class described composed of a series of rotary'members, some of which are mounted on the ties and others of which are located between the ties, all of said members having their tops in the same horizontal plane.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
